An Eigenvector Method for Surface Recovery
(The Eurographics Association, 2003)
In this paper we explore how spectral methods for graph seriation can be used to develop a new shape-fromshading algorithm. We characterise the field of surface normals using a transition matrix whose elements are computed ...
Lambertian Correction for Rough and Specular Surfaces
(The Eurographics Association, 2003)
This paper describes a method for performing Lambertian reflectance for rough and specular surfaces. Rather than using an existing reflectance model, we present a method for estimating the reflectance function from image ...
